我有这样的案文:
My arbitrary content....
```c#
public class Foo
{
//Some code
}
```
My other arbitrary content....
我想从以下开始找到所有障碍:
```c#
并结束:
```
and replace it with the content between these start and end tags, so that the result becomes:
My arbitrary content....
public class Foo
{
//Some code
}
My other arbitrary content....
How would that look?
